Deviation & Failure Case Studies – Page 3

Gowning deviation ignored during investigation – regulatory enforcement outcome

The incident began with an unusual uptick in positive microorganism samples from a sterile production area. Operators observed that the number of environmental monitoring excursions exceeded established limits. Additionally, internal…

Cross-contamination detected post-release during cleaning verification – patient safety risk case study

During a routine cleaning validation check, the quality control (QC) team identified an anomalous spike in particulate counts in the manufacturing suites. A batch of sterile injection products had already…

Sterility test failure misclassified during investigation – containment CAPA failure

The first indication of a problem concerning a sterility test failure is often seen through direct signals on the manufacturing floor or in laboratory results. In this case, the testing…

Cross-contamination detected post-release during investigation – containment CAPA failure

During a routine quality control (QC) evaluation, unexpected results emerged indicating potential cross-contamination in an aseptic product. The product in question was flagged during stability testing, revealing discrepancies in microbial…

Sterility test failure misclassified during media fill – containment CAPA failure

During a routine media fill for a sterile injectable, operators observed unexpected anomalies. The symptoms included:Click to read the full article.

Cross-contamination detected post-release during media fill – patient safety risk case study

During routine quality control checks, microbiological testing of a recently released media fill batch flagged unusual microbial growth. This unexpected result raised immediate concerns about the sterility of the batch,…

Cross-contamination detected post-release during media fill – regulatory enforcement outcome

The detection of cross-contamination often begins with unusual observations during routine quality control testing or manufacturing evaluations. In this particular case, a manufacturing facility producing sterile injectables experienced an unexpected…

Contamination source misidentified during investigation – patient safety risk case study

The initial signals of contamination in the specific case began with several batches of sterile products failing sterility testing. Laboratory results indicated non-conformance with sterility specifications, as growth of contaminants…

Sterility test failure misclassified during cleaning verification – regulatory enforcement outcome

The initial signals that indicated a potential sterility test failure included an increased number of deviations logged during routine sterility testing. Staff members reported discrepancies in sterility test results compared…

Gowning deviation ignored during media fill – patient safety risk case study

During a routine batch production in the aseptic filling area, an operator noticed visible contamination on the media fill vials, characterized by cloudiness and particulate matter suspended in the liquid.…

Media fill deviation not escalated during cleaning verification – regulatory enforcement outcome

Detecting symptoms of a potential media fill deviation begins at the operational floor and laboratory environment. Several indicators may signal a process deviation, including:Click to read the full article.

Gowning deviation ignored during cleaning verification – patient safety risk case study

In the wake of the gowning deviation, several signals were observed on the manufacturing floor:Click to read the full article.
